Resumo: There is evidence that climate change, particularly global warming, can alter the ideal ecological conditions for the survival of many pollinator species, especially small bees that reside in temperate environments. However, little is known how the rise in the average ambient temperature could affect the survival of large bees in tropical regions of the planet. In the present work, we investigated the thermoregulation process of the large carpenter bee Xylocopa frontalis nesting freely in rational nests that allow the direct measurement of its body temperature while performing the various activities necessary for its survival and reproduction in a tropical environment. The results showed that this species uses thermoregulation strategies such as heat loss by convection, evaporative cooling by dehydrating the nectar, and avoid foraging during the hottest times of the day, to avoid overheating and thrive in the studied area. However, it can be concluded that the areas where these bees live are on the threshold of the ecological conditions necessary for the survival of these bees and future climate changes, among them mainly the rise in environmental temperatures, can represent a serious risk for the survival of X. frontalis and other similar tropical species

Dissertação (Mestrado em Zootecnia) – Universidade Federal do Ceará, Fortaleza, 2020.http://www.repositorio.ufc.br/handle/riufc/53600There is evidence that climate change, particularly global warming, can alter the ideal ecological conditions for the survival of many pollinator species, especially small bees that reside in temperate environments.

No entanto, pouco se sabe como a elevação da temperatura média ambiente poderia afetar a sobrevivência de abelhas de grande porte nas regiões tropicais do planeta. No presente trabalho, investigamos o processo de termorregulação da abelha mamangava de grande porte Xylocopa frontalis, nidificando livremente em ninhos racionais que permitem a medição direta de sua temperatura corporal, ao desempenhar as diversas atividades necessárias à sua sobrevivência e reprodução em um ambiente tropical. Os resultados demonstraram que essa espécie usa estratégias de termorregulação, como a perda de calor por convecção, o resfriamento evaporativo por desidratação do néctar, e evitam forragear nos horários mais quentes do dia, para evitar o superaquecimento e prosperar na área estudada. No entanto, pode-se concluir que as áreas onde essas abelhas vivem estão no limiar das condições ecológicas necessárias à sobrevivência dessas abelhas, e mudanças climáticas futuras, dentre elas principalmente a elevação das temperaturas ambientais, podem representar um sério risco para a sobrevivência de X. frontalis e para outras espécies tropicais semelhantes.Comportamento de termorregulaçãoForrageamento.
